Abstract
Abstract-Fortification of enriched cereal grain flour products with folic acid has drastically reduced the prevalence of deficient plasma folate status, a major determinant of plasma total homocysteine (tHcy) levels. We hypothesized that even more liberally defined “suboptimal” plasma folate status might no longer contribute importantly to the population attributable risk (PAR) for mild hyperhomocysteinemia, a putative atherothrombotic risk factor. We determined fasting plasma tHcy, folate, vitamin B12, and pyridoxal 5?-phosphate levels, along with serum creatinine and albumin levels, in 267 consecutive patients (aged 61±9 [mean±SD] years, 76.4% men and 26.6% women) with stable coronary artery disease (CAD) who were nonusers of vitamin supplements or had abstained from supplement use for at least 6 weeks before examination. Subjects were evaluated a minimum of 3 months after the implementation of flour fortification was largely completed. Relative risk estimates for the calculation of PAR were derived from a multivariable-adjusted logistic regression model with ?12 ?mol/L tHcy as the dependent variable and with age, sex, pyridoxal 5?-phosphate (continuous), albumin (continuous), <5 ng/mL folate, <250 pg/mL vitamin B12, and ?1.3 mg/dL creatinine as the independent variables. The prevalence of ?12 ?mol/L plasma tHcy was 11.2% (30 of 267 patients). PAR estimates (percentage) for ?12 ?mol/L tHcy were as follows: <5 ng/mL folate (<1%), <250 pg/mL vitamin B12 (24.5%), and ?1.3 mg/dL creatinine (37.5%). In the era of folic acid–fortified cereal grain flour, renal insufficiency and suboptimal vitamin B12 status (but not folate status) contribute importantly to the PAR for mild hyperhomocysteinemia among patients with stable CAD.
Ueland et al step 1 has just said a good meta-data of fourteen possible training of dating anywhere between standard complete homocysteine (tHcy) accounts and you may (primarily) coronary artery problem (CAD) consequences inside inhabitants-centered cohorts; which meta-research are stated through the stop out-of 1999. This new aggregate cousin risk estimate (out-of all in all, 2786 instances) per 5 ?mol/L change in tHcy focus are 1.20 (95% CI step one.14 to just one.25). Nephrosclerosis, specifically renal arteriolar hyalinization, dos step three cuatro has been with the general arteriosclerosis dos and you will logical 3 together with subclinical CAD. 4 Discover an effective independent (inverse) organization ranging from glomerular filtration rate really determined by possibly iohexol approval 5 six otherwise 51 Cr-EDTA clearance 7 and you will accelerated tHcy accounts, and that encompasses glomerular filtration prices in the normative assortment. An effective surrogate to have glomerular filtration speed 8 and homocysteine age group, 9 creatinine is a significant determinant off tHcy profile for the CAD clients ten eleven and you will general communities. twelve Inside the a population-oriented shot that have mainly normal kidney means, fortification off enriched cereal cereals flour issues with folic acidic significantly faster brand new prevalence from lacking plasma folate status and you can lightweight hyperhomocysteinemia. thirteen Such studies contrast starkly towards the very restricted impact one this fortification policy has experienced for the prevalence out of lightweight hyperhomocysteinemia certainly one of chronic renal transplant readers, fourteen who act as a valid model into the hyperhomocysteinemia regarding chronic renal lack, typically. fifteen Moreover, kidney means measured as the a simple creatinine commitment ‘s the biggest separate determinant out of tHcy account when you look at the every one of these dos patient teams that have mild to help you modest chronic kidney insufficiency. 14 fifteen Into the white of such cumulative findings, 13 14 15 we hypothesized you to far more liberally defined “suboptimal” plasma folate updates might no lengthened contribute notably into population attributable exposure (PAR) to possess lighter hyperhomocysteinemia one of secure CAD patients. Appropriately, we examined fast plasma tHcy and you may serum creatinine and additional centered determinants regarding tHcy accounts (internet explorer, decades, sixteen gender, sixteen B-nutritional status, 16 and you will albumin 17 ) certainly one of 267 consecutive customers that have medically steady CAD, each of which was checked no less than three to four days immediately after fortification regarding enriched cereal cereals flour that have folic acidic try mainly finished. thirteen
